net: ionic: register PHC for rdma timestamping

Browse Source 
Currently, the driver only registers the PTP Hardware Clock (PHC) if
Ethernet hardware timestamping is supported. Update the registration
logic to register the PHC if the device supports either Ethernet
hardware timestamping or RDMA completion timestamping.
